Use the vertex form,
y=a(x-h)^2+ky=a(x+7)^2+45
<span>Use the y-intercept to solve for a</span>-200=a(0+7)^2+45
49a+45=-20049a=-245a=-5

Given that E=MC find E when M=20 and C =2.5<br><br>​
tresset_1 [31]

Answer:

50 or 125

Step-by-step explanation:

if u want E=MC then it would be 20 ×2.5=50

OR

if u what to find E=MC² then it would be 20×2.5×2.5 =125

ACCORDING TO ME THIS SHOULD BE THE ANSWER, BUT NOT QUITE SURE ABOUT THIS.

Hello, can you please review attached and help me with the answer ?
Elis [28]

Answer:

<em>(a). P(x) = 8x - 112,000 </em>

<em> (b). $80,000 </em>

Step-by-step explanation:

(a). P(x) = R(x) - C(x)

P(x) = 50x - 112,000 - 42x

<em>P(x) = 8x - 112,000</em>

(b). P(24,000) = 8(24,000) - 112,000  = <em>80,000</em>

----------------------------------------

(a). <em>P(x) = 8x - 112,000</em>

If cos(x)=1/4 what is sin(x) and tan(x)
anygoal [31]
You can use the identity
  cos(x)² +sin(x)² = 1
to find sin(x) from cos(x) or vice versa.

  (1/4)² +sin(x)² = 1
  sin(x)² = 1 - 1/16
  sin(x) = ±(√15)/4


Then the tangent can be computed as the ratio of sine to cosine.
  tan(x) = sin(x)/cos(x) = (±(√15)/4)/(1/4)
  tan(x) = ±√15


There are two possible answers.
In the first quadrant:
  sin(x) = (√15)/4
  tan(x) = √15

In the fourth quadrant:
  sin(x) = -(√15)/4
  tan(x) = -√15
